H3 video generation issue: phantom audio reads out prompt text

Vijayi · reddit · 2026-08-26

A user reported a glitch in generated videos (likely H3 model) where random voiceovers occur, reading phrases directly from the prompt or speaking unintelligible gibberish. This happens even when no speech is mentioned in the prompt. The user observed that camera direction instructions appended to the prompt are occasionally spoken aloud in the clip. Current settings: 0.4 guidance, 8 steps, baked-in LoRA checkpoint, 10-12s duration.
